CROSS-REFERENCE TO RELATED PATENT APPLICATIONS

This application is a Divisional of U.S. patent application Ser. No. 16/452,790, filed Jun. 26, 2019, which claims the benefit of and priority to U.S. Provisional Application No. 62/691,189, filed Jun. 28, 2018. The entire disclosures of the foregoing applications are hereby incorporated by reference herein.

BACKGROUND

This application relates generally to the field of adapters for fluidly connecting a plumbing fixture to a water supply. More specifically, this application relates to adapters having an adjustable length to accommodate the installation of the adapter to water supplies having outlets located at various depths behind a finished wall surface.

Generally, wall-mounted plumbing fixtures (e.g., shower heads, tub fillers, etc.) are coupled to a water supply via a small opening in a wall to which a plumbing fixture is attached. During installation of the plumbing fixture, a first threaded end of a pipe nipple (e.g., male-male) is attached to a standardized national pipe thread (“NPT”) formed about an interior of an elbow outlet of the water supply. A second threaded end of the pipe nipple is attached to the plumbing assembly, and fluidly couples the plumbing fixture to a water supply line of the water supply.

The installation of a plumbing fixture using a pipe nipple suffers a number of drawbacks. For example, as noted above, water supply outlets are often installed at different (e.g., non-standardized) depths relative to the outer surface of a wall. Additionally, it may difficult for an installer to ascertain the depth at which an outlet is located prior to the installation of a plumbing fixture, as such a determination typically requires uninstalling (and decommissioning) an existing plumbing fixture that is coupled to the outlet. Thus, unless a variety of pipe nipples of differing lengths are readily available during the installation of a new plumbing fixture, the installation of the plumbing fixture may be delayed until an appropriately sized pipe nipple is located, increasing downtime of the bathroom or other space (e.g., a sanitary space).

Installation of a pipe nipple is often also complicated by the short length of a pipe nipple. In particular, upon installation, the pipe nipple may be located entirely behind a wall. Given the limited access to a rear portion of a wall provided by the opening in the wall, the ability of an installer to use tools (e.g. a wrench, pliers, etc.) to install the pipe nipple without damaging the wall may be limited.

The dual-threaded configuration of a conventional pipe nipple also may present problems during the installation of a plumbing fixture. Notably, installing a plumbing fixture with a non-circular cross-sectional profile in a correct orientation—while also ensuring that the plumbing fixture is disposed directly against the outer surface of the wall—often requires that the threads on one or both ends of the pipe nipple not be fully threaded into corresponding threading on one or both of the elbow and the attachment structure of the plumbing fixture. This partial engagement of the threading of the pipe nipple to one or both of the plumbing fixture and water supply reduces the quality of the seal between these components. The adverse effect on the seal between the adapter and one or both of the plumbing fixture and water supply may be compounded if the pipe nipple includes a tapered threaded section, as the smaller diameter at the first end of the thread on the pipe nipple may not be large enough to properly engage the inner threads of the elbow outlet and/or the inner threads of the plumbing fixture conduit.

It would therefore be advantageous to provide an adapter with an adjustable length for connecting a plumbing fixture to a water supply line. In particular, it would be advantageous to provide a single adapter that can be cut to different desired lengths.

DETAILED DESCRIPTION

Referring generally to the FIGURES, an adapter configured to minimize the effort, time, and inconvenience typically associated with the installation of a plumbing fixture to a water supply assembly using conventional connector conduit structures (e.g., a pipe nipple) is shown and described according to various embodiments. The adapter includes a plurality of individually separable collars that allow for easy, on-site adjustment of the length of the adapter based on a measured offset of an elbow outlet at the installation location. Thus, the adapter obviates the need for an installer to stock a plurality of connector conduits of varying lengths to avoid delays caused by the unavailability of an appropriately sized connector during the installation of the plumbing fixture. An exterior of each collar is configured to sealingly engage the outlet opening (e.g. elbow outlet) of a water supply assembly, such that the adjustment to the length of the adapter does not compromise the ability of the adapter to be sealingly coupled to the water supply assembly.

The length of the adapter—which is configured to extend beyond the outer surface of the wall upon installation—minimizes (or does not require) the need for a user to maneuver tools through a narrow opening in the wall to couple the adapter to the water supply assembly. In addition to simplifying the installation of the adapter to the water supply assembly outlet, the installed configuration of the adapter relative to the exterior of the wall minimizes the risk of damage to the wall during installation of the plumbing fixture. A slip fitting provided along the adapter allows the plumbing fixture to be installed flush against a wall in a desired orientation, without compromising the sealing engagement between the adapter and either of the plumbing fixture or outlet opening.

Turning to FIG. 1, a water supply assembly 10 via which wall-mounted plumbing fixtures (e.g., shower heads, tub fillers, etc.) are typically plumbed to a water source is shown according to an exemplary embodiment. As shown in FIG. 1, the water supply assembly 10 includes a water supply line 20 and an elbow 22 (or other connector). The water supply line 20 and elbow 22 are each located and concealed (e.g. hidden) behind the wall 12.

The water supply line 20 delivers water from a water source to a location at which the plumbing fixture is installed. An elbow inlet 26 (e.g., first end, upstream end, etc.) is attached to a downstream end 24 of the water supply line 20 and redirects water therefrom towards an outer surface 14 (e.g., first, front, exterior) of the wall 12. The elbow inlet 26 includes an engagement structure configured to engage a corresponding engagement element provided on the downstream end 24 water supply line 20. For example, an interior of the elbow inlet 26 includes an internally extending standardized national pipe thread (“NPT”) that is configured to engage a corresponding threading provided on an exterior of downstream end 24 of the water supply line 20.

As shown by FIG. 1, the elbow outlet 28 (e.g. second end, downstream end, etc.) is oriented opposite an opening 18 (i.e., hole, orifice, etc.) extending between the outer surface 14 and an inner surface 16 (e.g., second, rear, interior) of the wall 12. Access to the elbow outlet 28 and the rest of the water supply assembly 10 located behind the wall 12 is typically limited to that provided by the opening 18. The opening 18 thus defines a passageway via which the plumbing fixture is fluidly coupled to an engagement structure (e.g. internal threading) provided by the elbow outlet 28.

A length of the connector conduit (e.g. the adapter 40) required to couple a plumbing fixture to the elbow 22 corresponds to a distance L_(offset) by which the elbow outlet 28 is offset from the outer surface 14 of the wall 12. The spacing (e.g. lateral offset) between the elbow outlet 28 and the outer surface 14 of the wall 12 is not standardized, and may vary between different installation locations.

Turning to FIGS. 2 and 3, an adapter 40 configured to facilitate the fluid coupling of a plumbing fixture to a water supply assembly 10 is shown according to an exemplary embodiment. As described below, the adapter 40 incorporates a number of features configured to minimize the effort, time, and inconvenience typically associated with the installation of a plumbing fixture to a water supply assembly 10 using conventional connector conduit structures (e.g., a pipe nipple).

As shown in FIG. 2, the adapter 40 includes a substantially annular body 42 that extends between a first end 44 (e.g., an upstream end) and a second end 46 (e.g., a downstream end). A bore 62 configured to pass water therethrough extends through the annular body 42 between the first end 44 and the second end 46.

A plurality of annular collars 48 are integrally provided along the length of the annular body 42. The collars 48 are separable (e.g., from one another, from the annular body 42, etc.), and are configured to allow a user to adjust a length of the adapter 40 as needed during the installation of a plumbing fixture. As shown in FIG. 3, the collars 48 and annular body 42 are integrally formed (e.g. molded, cast, etc.) as a single, monolithic structure. However, some or all of the collars 48 may instead be discrete elements that are integrally coupled (e.g., soldered, welded, threaded, adhered, or otherwise attached) along the exterior of the annular body 42.

Each of the collars 48 defines a length L_(collar) measured from a first end 50 (e.g. upstream end) to a second end 52 (e.g., downstream end). The collar length L_(collar) may be standardized (e.g., approximately 0.5 inches) for all the collars 48, or may vary between some or all collars 48. An engagement structure (e.g. external threading) capable of fluidly coupling the adapter 40 to an elbow outlet 28 is provided along an exterior of each collar 48. As such, the modification of the length of the adapter 40 via the selective removal of one or more collars 48 does not compromise the ability of the adapter 40 to sealingly engage the elbow outlet 28.

The arrangement of the collars 48 relative to the annular body 42 and/or the type and arrangement of an engagement structure about each collar 48 may be varied to correspond to the particular configuration of a water supply assembly 10 to which the adapter 40 will be connected. For example, although the collars 48 are shown in FIGS. 2 and 3 as being externally threaded and provided along the exterior of the annular body 42 (e.g., define a male configuration), the collars 48 may instead be provided along the interior of the annular body 42 (e.g. define a female configuration), and the engagement structures of the collars 48 may include structures other than external threads.

The plurality of collars 48 are arranged in series downstream (e.g. inwards) from the first end 44 of the annular body 42 so that the first end 50 of a collar 48 is positioned opposite to a second end 52 of an adjacent collar 48. The first end 50 of each collar 48 defines an outer diameter D₁ that is less than an outer diameter D₂ of the second end 52 of the respective collar 48. Accordingly, as shown in FIG. 3, the dimensions of the exterior surface of each collar 48 varies (e.g. tapers linearly) between the first end 50 of a collar 48 and the respective second end 52 of the collar 48. The tapered configuration of the exterior surfaces of a collars 48 allows the collar 48 to adapt to variations in the diameters defined by elbow outlets 28 at different locations at which adapter 40 may be installed. Thus, the non-uniform external diameter of each collar 48 is configured to increase the compatibility the adapter 40 with elbows 22 (or other connectors) of various sizes.

Although FIGS. 2 and 3 show the first ends 50 of each collar 48 having substantially equally sized outer diameters D₁ and the second ends 52 of each of the collars 48 having substantially equally sized outer diameters D₂, the first and second outer diameters D₁, D₂ may be different for some of the collars 48. Additionally, although the exterior surfaces of the collars 48 are described as defining non-uniformly sized exterior surfaces that taper linearly between at first end 50 of a collar 48 and a respective second end 52 of the collar 48, the first and second outer diameters D₁, D_(2 of) some or all of the collars 48 may instead by substantially the same as one another.

The first end 50 of a collar 48 is separated (e.g., spaced apart, laterally offset, etc.) from the second end 52 of an adjacent collar 48 by an annular recess 54 (e.g., inset portion, exposed portion of an exterior of the body channel, groove, slot, kerf, etc.). For example, a recess width W_(recess) that is greater than zero is defined between the second end 52 of a first collar 48 and an adjacent first end 50 of a second collar 48. As shown in FIG. 3, the portions of the adapter 40 exterior corresponding a recess 54 are defined by an outer diameter D_(recess) that is less than each of the first outer diameter D₁ of a collar 48 and the second outer diameter D₂ of an adjacent collar 48 between which the recess 54 extends.

The recesses 54 extending between adjacent collars 48 provide a visual indicator via which an installer may more easily recognize locations along the annular body 42 at which the adapter 40 is to be cut to attain a desired adapter 40 length. Additionally, upon engagement of a collar 48 to the elbow outlet 28, the smaller diameter D_(recess) of the recess 54 as compared to the first outer diameter D₁ of the collar 48 serves to isolate (e.g., space apart, vertically offset, etc.) the elbow outlet 28 from the outer profile of the recess 54. This isolation of the elbow outlet 28 form the outer profile of the recess 54 minimizes (or prevents) any deformation (e.g., shards, disruptions, anomalies etc.) of the outer profile of the recess 54 that may have been caused by the adjustment of the length of the adapter 40 from interfering in the engagement between the collar 48 and elbow outlet 28.

To further assist a user in customizing the length of the adapter 40, a thickness of the adapter 40 at locations corresponding to recesses 54 is less than a thickness of the adapter 40 at locations along which a collar 48 extends. This reduced thickness of the adapter 40 at the annular recesses 54 allows an installer to more easily cut through (e.g. detach, separate, etc.) a recess 54 during the adjustment of the adapter 40 length.

The second end 46 of the adapter 40 includes an engagement structure (e.g. fitting) configured to sealingly engage a plumbing fixture. The second end 46 of the adapter 40 may be defined by a variety of different engagement structure configurations. For example, as shown in FIGS. 2 and 3, the second end 46 of the adapter 40 comprises a slip fitting that includes a plurality (e.g. two) annular channels 56 formed within an exterior of the annular body 42. A gasket 58 (e.g., an O-ring) is supported within each channel 56, and extends radially outwards relative to an exterior of a portion of the annular body 42 located adjacent the channels 56 (see FIG. 5). The gaskets 58 are configured to engage an interior of a corresponding attachment structure of a plumbing fixture to sealingly couple the adapter 40 to the plumbing fixture upon installation of the plumbing fixture to the adapter 40.

In contrast to the rotational movement required to engage a plumbing fixture to an external thread of a conventional pipe nipple, a slip fitting of the adapter 40 allows the plumbing fixture to be coupled to the adapter 40 using only a linear, sliding movement of the plumbing fixture relative to the adapter 40. Thus, the slip fitting of the adapter 40 allows the plumbing fixture to be installed flush against the outer surface of the wall 12 and in a desired clocked (e.g. aligned) orientation, without compromising either the sealing engagement between the adapter 40 and elbow outlet 28, or the sealing engagement between the adapter 40 and the plumbing fixture.

Referring again to FIG. 3, installation of the adapter 40 to a water supply assembly 10 may further be facilitated by an optional driving feature 60 that is operationally provided about an interior of the second end 46 of the adapter 40. The driving feature 60 includes a standardized structure configured to engage an installation tool received therein. For example, the driving feature 60 includes a hexagonal opening configured to receive a hex key or a socket to assist a user in rotating the adapter 40 until the first end 44 of the adapter 40 is fully threading engaged with the elbow outlet 28.

The improved and simplified installation of a plumbing fixture to a water supply line 20 using the adapter 40 is described according to an exemplary method with reference to FIGS. 4 and 5. According to various embodiments, the adapter 40 is used during the retrofitting (e.g. replacement) of a water supply assembly 10 with a new plumbing fixture. Thus, as an initial step of the installation of the new plumbing fixture, an existing plumbing fixture (e.g., the spigot 30 of FIG. 4) is decoupled from the water supply assembly 10.

Given the non-standardized range of depths by which the elbow outlet 28 may be offset from the outer surface 14 of a wall 12, a next step in the installation of a plumbing fixture includes determining (e.g. measuring) the offset distance L_(offset) of the elbow outlet 28 at the installation location. In the event that the water supply assembly 10 incorporates a connector structure other than an elbow 22 to which the adapter 40 is to be coupled, the offset distance L_(offset) instead corresponds to a distance between the outer surface 14 of the wall 12 and the connector structure.

The determined offset distance L_(offset) is used to identify a recess 54 along which to cut the adapter 40 so that a length L_(adapter) of the resultant shortened adapter 40 will allow the adapter to fluidly couple the plumbing fixture to the water supply assembly 10. Notably, the modified adapter length L_(adapter) is typically greater than the offset distance L_(offset), such that at least a portion of the second end 46 of the annular body 42 extends beyond the outer surface 14 of the wall 12 upon installation of the adapter 40 in the elbow outlet 28 (see, e.g., FIG. 5).

The length L_(adapter) to which the adapter 40 is cut is dependent on the offset distance L_(offset) of the elbow outlet 28. Additionally, the length L_(adapter) to which the adapter 40 is cut may vary based on the exposed length of the adapter 40 required for the coupling of the engagement structure (e.g. the slip fitting) of the adapter 40 to a corresponding attachment structure provided by the plumbing fixture.

For example, in embodiments in which the adapter 40 is provided separately from any specific plumbing fixture (e.g. the adapter 40 is used by an installer to install various types of plumbing fixtures), installation of the adapter 40 may also require that the required exposed length of the plumbing fixture being installed be determined (e.g. measured) by the installer. This required exposed length of the adapter 40 is equal to a distance between a mounting structure (e.g. base, plate, escutcheon, etc.) of the plumbing fixture and the attachment structure of the plumbing fixture via which the plumbing fixture is attached to the adapter 40. Once the combined offset distance L_(offset) and required exposed adapter 40 length have been obtained, the adapter 40 is cut along a recess 54 that is defined by, or which is located immediately upstream from (i.e. located closer to the first end 44), a location along the annular body 42 that is separated from the second end 46 of the adapter 40 by the combined sum of the offset distance L_(offset) and required exposed length of the adapter 40.

In embodiments in which the adapter 40 is configured to be used with a particular plumbing fixture model (e.g., the adapter 40 is supplied together with a plumbing fixture), the required exposed length of the adapter 40 is defined by a constant, known distance, and does not vary between different locations at which the adapter 40 and plumbing fixture are installed. In such embodiments, the recess 54 at which the adapter 40 is to be cut may accordingly be identified using only a measured offset distance L_(offset) of the elbow outlet 28 at the installation location. A chart associating specific ranges of offset distances L_(offset) with a recesses 54 along which to cut the adapter 40 (or a number of collars 48 to be removed from the adapter 40) allows an installer to quickly identify the appropriate number of collars 48 that are to be removed (or a recess 54 along which the adapter 40 is to be cut) upon determining the offset distances L_(offset) of the elbow outlet 28. Markings (e.g. embossing or printing provided on the recesses 54; colored bands attached about the recesses 54, etc.) indicating a range of offset distances L_(offset) that each recess 54 corresponds to may additionally (or alternatively) be formed or provided directly along the recesses 54 to further simplify the identification of a location at which the adapter 40 is to be cut.

Once the recess 54 along which the adapter 40 is to be cut (or the number of collars 48 to be removed) has been identified, the adapter 40 is cut fully through the identified recess 54 until any collars 48 located upstream from the identified recess 54 (i.e. between the identified recess 54 and the first end 44 of the adapter 40) are separated from a remaining portion of the annular body 42. This process shortens the overall length of the adapter 40 to a length L_(adapter that) is configured to correspond to the requirements for installing the plumbing fixture at the desired installation location.

Following the adjustment of the adapter 40 to the desired installation length L_(adapter), the adapter 40 is engaged to the elbow outlet 28 of the 22 (see FIG. 5) by an endmost collar 48 of the modified adapter 40 (i.e. a collar located adjacent the upstream end of the modified length adapter 40), and the plumbing fixture is attached (e.g. slid onto) to the exposed portion of the adapter 40 to install the plumbing fixture to the water supply assembly 10.
